Iron is sold in sheets that are 2.0 cm thick and 120.0 cm wide. You want to buy
a sheet of iron with a mass of 50,000.0 g. What must be the length of the
sheet of iron?

Best ResponseYou've already chosen the best response.0I would say not enough information because you don't have the amount of grams for the given dimensions.

Best ResponseYou've already chosen the best response.0you can solve this if you know the density of iron (which was likely in a previous problem for you). from google, d=7.874 g/cm^3 Now using the density formula, we know we need the volume and the mass. We were given a mass, but no volume, but two dimensions, we know the formula for volume for a rectangular prism is \(V=l*w*h\) (thickness is height here). so we sub in and solve for length. \(\sf d=\dfrac{m}{V}=\dfrac{m}{l*w*h}\rightarrow l=\dfrac{m}{d*w*h}=\dfrac{50,000.0 ~g}{7.874 g/cm^3*2 ~cm*120.0~cm }\)
